Maeda MC-305C-2 - Operation in Crane Mode

6-43
8.3 OPERATION IN CRANE MODE
• Ensure that all the outriggers are properly installed.
Where outriggers are improperly installed, it may result a serious hazard, such as a Crane
tipping.
• During crane operations, always refer to the portable rated total load chart and avoid
over-loaded operations. Operations in over-loaded conditions may damage or tip the Crane,
which results a serious hazard.
• Check the smooth and correct actions of each operation lever of the Transmitter, and that they
smoothly return to the each neutral position when the finger is released.
• Each operation lever of the Transmitter will be blocked by its stopper when it is moved full.
When it is blocked, do not attempt to push more, otherwise it may damage the Transmitter and
cause its fault; it may result a serious accident.
• To toggle each operation lever to the opposite side, or to use another lever, always release the
Accelerator lever, each time. Also, to operate the Crane, manipulate the operation lever first,
then pull the Acceleration lever, next. To stop the operation of the Crane, release your finger
from the Accelerator lever, first, and next discharge the operation lever.
• Always actuate the Accelerator lever with caution to the acceleration rate.
It must be properly controlled to keep the appropriate crane operation speed and avoide any
abrupt motion. Such abrupt acceleration or deceleration especially while a load is hung will
make a large impact to the Crane and may result a serious hazard such as Crane tipping or
damage.
• During a load is hung, do not attempt to perform multiple operation at a time, the hook raising
and the boom derricking, for instance. That may cause abrupt change of the load condition
and cause a serious hazard such as the Crane tipping or damage.
1. Ensure that the main switch of the Receiver is in the OFF
position.
2. Start the engine by the Starter switch of the Crane.
3. Push the Power switch of the Transmitter to power ON.
Confirm that the LCD screen shows the mark as the figure in the
right and the “CRANE MODE” is automatically provided.
4. Then turn ON the Main switch of the Receiver.
The voice message will call you as “Remote control is ready”.
NOTES
When the main switch of the Receiver is turned ON, the
abnormal signal detector circuit works for 3 to 4 seconds. During
this moment, the Crane is not ready for operations.
NOTES
Four of the Crane operation levers are provided. Each controls
the following operation, respectively. (See the figure in the
right.)
(1): Slewing (upper: counterclockwise, lower: cloackwise)
(2): Boom telescoping (upper: extend, lower: retract)
(3): Hook rasing and lowering (upper: raising, lower: lowering)
(4): Boom derricking (upper: raising, lower: lowering)
